Abstract: PROBLEM TO BE SOLVED: To make constant the heat quantity supplied to the hair and make uniform the curling or uncurling of the hair, by making a heat emitting body generate heat so that the temperature of the end parts of a hair winding drum is higher than that of the central part. SOLUTION: The heat emitting body 2 is made from a single sort of material and is formed cylindrical, and the parts positioned at the two ends of a hair curler 3 have a small wall thickness and the wall thickness is incremental toward the center. When current is fed, the heat emitting body 2 has a higher temp. at the ends than in the central part, but when the hair curler 3 is removed after the current feed, the two ends emit a large quantity of heat, and therefore, the temp. in different parts of a hair winding drum after the removal becomes even, and it is possible to give a uniform quantity of heat to the hair. According to this configuration, it is possible to make approx. the same the temp. of the end parts emitting a large heat and the central part emitting small heat after the current feed.  In this manner, the heat quantity supplied from the hair curler 3 to the hair can be made constant, so that the curling and uncurling of the hair can be performed evenly.

Title: Noise eliminating device
Inventor: ONO YUTAKA
IPC: G05B11/36
Filed: 1985-04-30
Abstract: PURPOSE:To eliminate noise included in the output of a controller at a high attenuation rate by subtracting the output of a noise estimator which estimates the noise component from a true estimated value of a speed signal of the output of an observer. CONSTITUTION:When a speed signal Vf from a speed signal generating circuit 5 is inputted to a speed observer 6, high band noise is suppressed. The signal Vf from the circuit 5 and an estimated speed feedback signal from the observer 6 are inputted to a noise estimator 7, and the noise estimator 7 subtracts the latter from the former to output an estimated noise value. A subtractor 8 subtracts this estimated noise value from an estimated speed feedback signal of the observer 6 to feed back the estimated speed feedback signal, where the noise component is eliminated approximately completely, to the second feedback point. The output of a controller 1 is compared with a feedback position signal from a position feedback gain circuit 4 and the estimated speed feedback signal at the second feedback point, and the results are applied to a controller 30. By this device, not only the speed feedback signal has the noise eliminated by the observer 6 but also the noise remaining in the output of the observer 6 is eliminated with the output of the estimator 7.
